Intel Celeron G5920 vs Intel Core i7-3537U Comparison

The Intel Celeron G5920 and the Intel Core i7-3537U represent two very different approaches to dual-core computing. The G5920 is a modern desktop part built for raw clock speed, while the i7-3537U is an older, power-efficient mobile chip designed for ultraportable laptops. The benchmark data shows a consistent pattern: the desktop Celeron outperforms the mobile i7 in every recorded Cinebench test, despite the i7 having double the threads. This analysis examines the architectural roots of that performance gap and what it means for potential users.

FAQ

Q: Which processor has a higher base clock speed?

A: The Intel Celeron G5920 has a base clock of 3.50 GHz, while the Intel Core i7-3537U has a base clock of 2.00 GHz. The i7-3537U does feature a boost clock of 3.20 GHz, but the Celeron's base clock is still higher than the i7's maximum boost.

Q: How does the Core i7-3537U's thread count compare to the Celeron G5920's?

A: The Core i7-3537U has 4 threads (2 cores with Hyper-Threading), while the Celeron G5920 has only 2 threads (2 cores without Hyper-Threading). This gives the i7 a theoretical advantage in multi-threaded workloads, yet the benchmark results show the Celeron still wins.

Q: What is the performance difference in the Cinebench R23 multi-core test?

A: The Celeron G5920 scores 2252 points, which is 12.7% higher than the i7-3537U's score of 1998 points. This is the largest absolute score gap between the two processors in any shared test.

Q: Which processor has a larger L3 cache?

A: The Intel Core i7-3537U has a 4 MB shared L3 cache, double the 2 MB shared L3 cache found on the Intel Celeron G5920. The i7 also has a larger die size at 118 mm², compared to the Celeron's unspecified die size.

Q: Do both processors support ECC memory?

A: No. Both the Intel Celeron G5920 and the Intel Core i7-3537U have ECC memory support set to false, meaning neither processor supports Error-Correcting Code memory.

Q: What is the average benchmark score for each processor?

A: The Celeron G5920 has an average benchmark score of 775, while the i7-3537U has an average score of 766. Both processors sit at the 21st percentile of all CPUs in the database.

Architecture Differences

The two processors come from different Intel eras and design philosophies. The Celeron G5920 is built on the Comet Lake architecture using a 14 nm process node, while the i7-3537U is based on the older Ivy Bridge architecture on a 22 nm node. This generational gap explains several fundamental differences.

The Celeron G5920 is a desktop processor with a TDP of 58 W, designed for the Intel Socket 1200 platform. It supports DDR4 memory with dual-channel configuration and has a memory bandwidth of 42.7 GB/s. The i7-3537U, by contrast, is a mobile processor with a much lower TDP of 17 W, designed for the Intel BGA 1023 socket. It supports DDR3 memory, also in dual-channel configuration, but has no recorded memory bandwidth figure.

Cache configurations differ significantly. Both processors have 64 KB of L1 cache per core and 256 KB of L2 cache per core. However, the i7-3537U has 4 MB of shared L3 cache, while the Celeron G5920 has only 2 MB. The i7 also has a recorded die size of 118 mm², which is larger than what a 14 nm dual-core part would typically require, though the Celeron's die size is not listed.

Integrated graphics also set the two apart. The Celeron G5920 uses UHD 610 graphics, while the i7-3537U integrates Intel HD 4000 graphics. The Celeron supports PCIe Gen 3 with 16 lanes from the CPU, whereas the i7's PCIe configuration is not recorded in the database.

The manufacturing dates reflect their respective positions in Intel's lineup. The i7-3537U was released in January 2013, while the Celeron G5920 arrived in April 2020. The Celeron remains in active production, while the i7's production status is not listed.

Head-to-Head Benchmarks

The database records five head-to-head Cinebench comparisons between these two processors, and the Celeron G5920 wins all five. The margin is remarkably consistent, ranging from 12.4% to 12.8% across all tests.

In the Cinebench R15 multi-core test, the Celeron G5920 scores 226 points against the i7-3537U's 201 points, a 12.4% advantage. This test is particularly telling because the i7 has 4 threads to the Celeron's 2 threads, yet the Celeron still wins by a significant margin.

Moving to Cinebench R20, the multi-core test shows the Celeron at 945 points versus the i7's 839 points, a 12.6% lead. The single-core test in R20 shows a similar gap: 133 points for the Celeron against 118 points for the i7, a 12.7% difference. This single-core result highlights the impact of the Celeron's much higher base clock of 3.50 GHz versus the i7's 2.00 GHz base clock.

The Cinebench R23 results continue the trend. In the multi-core test, the Celeron scores 2252 points against 1998 points for the i7, another 12.7% advantage. The single-core test shows the Celeron at 318 points versus 282 points, a 12.8% gap, which is the largest percentage difference in any recorded test.

The consistency of these margins is noteworthy. Across five different test versions and workload types, the performance delta stays tightly clustered between 12.4% and 12.8%. This suggests the advantage is structural, rooted in the Celeron's higher clock speeds and newer architecture, rather than test-specific quirks.

The i7-3537U does have additional benchmark data in the database, including Geekbench scores of 1269 for multi-core and 658 for single-core, but the Celeron G5920 lacks corresponding Geekbench results. Therefore, no direct comparison can be made on that test platform.

The Verdict

The benchmark data presents a clear picture: the Intel Celeron G5920 is the faster processor in every measured workload. Despite having half the threads of the i7-3537U, the Celeron's higher base clock of 3.50 GHz and newer Comet Lake architecture deliver a consistent 12.4% to 12.8% performance advantage across all Cinebench versions.

For users prioritizing raw compute performance in desktop applications, the Celeron G5920 is the stronger choice. Its 58 W TDP and Socket 1200 platform indicate a desktop-focused design where power consumption is less critical than performance. The Celeron also supports faster DDR4 memory with a recorded bandwidth of 42.7 GB/s, which can further benefit memory-sensitive workloads.

The i7-3537U's case rests on different strengths. Its 17 W TDP makes it dramatically more power-efficient, consuming roughly one-third the power of the Celeron. This makes it suitable for mobile platforms where battery life and thermal constraints are paramount. The i7 also offers double the L3 cache (4 MB versus 2 MB), which could benefit certain cache-sensitive workloads, though the benchmark data does not show this translating into a performance win.

The i7-3537U's 4 threads provide better multi-threading capability than the Celeron's 2 threads, but in practice, the Celeron's clock speed advantage overcomes this. The i7's boost clock of 3.20 GHz still falls short of the Celeron's 3.50 GHz base clock, meaning the Celeron maintains a clock advantage even when the i7 is at maximum boost.

Neither processor stands out in the broader market. Both sit at the 21st percentile of all CPUs, and their average benchmark scores (775 for the Celeron, 766 for the i7) place them within a tight cluster of similarly performing parts. The database shows the Celeron matching the Intel Core i3-3250T exactly at 775 points, while the i7-3537U sits near the AMD A8-6600K at 764 points.

The choice ultimately depends on platform and power requirements. For a desktop build where performance per watt is less critical, the Celeron G5920 offers superior compute performance. For a mobile or low-power application where the 17 W TDP and BGA 1023 socket are required, the i7-3537U remains a viable, if slower, option.
